two of the malfunctions were due to the mag not being fully seated, the other two were ammo and my experimental buffer problems --which i had to go back the the drawing board with.

accuracy is very good, reasonable power for a 9mm from that 16" stainless barrel. very quiet. recoil is there and not as light as you would think for 9mm. probably enough for a bump-fire set up. when TA drops by we'll see if the 9er will do for that.

it is an impressive little shooter. but it is another learning curve compared to gas operates irons.

everybody else gripes about the c-products 9mm mags , i can't say i am having any problems with them provided their fully seated before you start firing.

insert the mag from an open bolt and i"m having no mag related problems to speak of so far.

with so called "assault rifle" ammo getting expensive i'll be shooting the 9 mikey-mike a bit more.

only thing is it can't reach way out there, it ain't like i got nothing that will reach out there on the rack though.

Glad your 9mm is running well. I did the 9mm AK thing, and that will have to suffice for now. Would love to build a 9mm AR, but it's just not on the short list at the moment. We'll see how things play out in November, and maybe next Spring.......

I would love to see the work as I have been thinking about one in .40 S&W or .45.

Colt has used at least two different 9 mm buffers. They both weigh the same but the early one is called a "two piece" buffer and the later one is called a "one piece" buffer. A lot of people want the two piece buffers because they are suppose to be fairly reliable in the 5.56 without needing to change them. The later one piece buffer is considered much less reliable in 5.56, even though both 9 mm buffers weigh the same and are black in color.

The early Colt semi auto bolt didn't have an opening in the top of them for the regular hammer. They require the short, semi auto 9 mm hammer to clear the top of the bolt. Using the select fire or later semi auto Colt bolt with a smooth face M16 hammer can go full auto if the disconnector breaks. The step on the semi auto hammer will catch and won't ride the firing pin hard. I have read about the "ramped" 9mm bolts that are suppose to allow using the 5.56 semi auto hammer. Without the ramp, the step in the semi auto 5.56 hammer face catches the bolt on the recoil stroke I think but I haven't tried combining those parts. My magazines are Colt magazines. Colt had a problem with the 9mm bolts traveling so fast that they would break the disconnector or the pins in the FCG with the hammer crashing down on them. Colt upgraded the steel in the FCG pins in the 9 mm models and later in the 5.56 models. These are the silver pins. I'd build another 9mm AR15 but I need to know which bolt and hammer to use these days.

the overly fast bolt is a problem with my build . the ramped bolt seems fine with a standard semi hammer i am just running a DPMS FCG.

what i'll probably do is cut down and add weight to a rifle buffer.

the high speed of the blow back bolt can cause carrier bounce if not buffered and sprung the right way.

right now it seems OK with a long recoil spring and one of my pals that is an expert on the 9mm told me i can shim the recoil spring up a little.

i had thought of doing a 357sig or 40S&W as well.

either of these are going to require some strong recoil springs and some heavy special buffers.

i am thinking the 357sig would be better if it was gas operated like a regular ar-15---

A bottleneck cartridge, especially a high pressure one, not only has the recoil force on the bolt but also the expansion of the case neck pushing against the chamber shoulder. I did make a 357 Sig Uzi. I reamed a commercial, non-chrome lined barrel. At first I tried 41 Action Express magazines but the 9 mm Uzi magazines worked better and worked well. I used a semi auto 45 ACP Uzi bolt with a 9 mm Uzi extractor. It was a perfect fit.
